CONNECTOR ATTACEENT FOR BATTERIES;

- useful Improvements in Connector Attachments for Batteries; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference be- I ing had to the accompanying drawings, and

Wl110l1 form a part of to the letters of reference marked thereon,

this specification. This invention relates to new-and useful improvements in attachments for dry and wet batteries for connecting electric wires thereto and consists in the provision of a draw spring having a coil, one end of which is embedded in the parts of the battery and affording means whereby a connector wire maybe held indifferent positions intermediate the coils of the'spring. By this arrangement of the'wire in the carbon of the battery, the full utility of the latter isobtained without any loss of power' due to loosened screws and short'connections upon theusual batteryas now constructed.

The invention comprises. various details of construction, combinations and arrangements of parts which will be hereinafter fully described and then specifically defined in the appended claim. j

illustrate my invention 1n the-accompanying drawings, in which:

Figure 1 is a perspective View of a battery showing my coiled-draw sprlng as attached thereto, and Fig. 2 is a sectional view through the carbon, showing the manner of anchoring the wire, out of which the spring is formed, thereto.

Reference now beinghad to the details of the drawings by letter, A designates a battery of any. usual construction, either wet or dry, and is provided with a carbon B.

Y C designates a resilient wire which is embedded in the compact carbon and is preferundulating or curved in order to make ably a more secure anchorage therein. Said wire runs substantially thelength of the carbon Specification of Letters Patent.

and its upper end is formed into a coil D, the

which are normally held together. E desig held frictionally between any of the convolutions of the coil, thereby effecting a sure in difl:'erent positions.

G designates/a connector Wire which has one end preferably soldered to the zinc of the battery, thus dispensing with screws, etc., which entail an expense and trouble to persons by becoming loose, producing interrupted currents, etc.

coiled spring the end of said sprlng having a bearing against the lower face ofthe knob affording means whereby a person may cause the coil to expand or separate for the insertion of the connecting Wire between the convolutions thereof and, after the knob is released, the tension of the coil will cause the connecting wire to be securely clamped and held in any desired position.

tion resides in the fact that no chance in making a mistake in connecting up the batteries is possible, as it would be impossible to connect two carbons together or two zines thereby preventing all short circuit.

By the provision of attachments to batpacked without obstructions commonly placed, such as binding posts, etc., which are ikely to be broken or lost and a less space is required in battery boxes by the attachment forming the subject matter of the present application. v

Itwill be understood that the draw spring which is anchored to the carbon maybe made of any suitable metal and, if desired, a draw desirable or vice versa by placing 2. connecting wire on the carbon and the spring on the zinc.

What I claim to be new is e In combination with'a dry battery, a carbon therein,-a draw spring hav ng a portion thereof undulating and embedded in said A knot His formed at the upper end of the An important feature of the present invenas they will not fit in the regular routine,

teries as shown and described, an advantage is obtained in that they may be conveniently;

spring may be placed on the zinc if found nates a connector .wire which is I contact and said connecting wire may be held carbon and extending substantially its In testimony whereof I hereunto afiix my length, a portion of said spring which exsignature in the presence of tWo witnesses. tends through the end of the carbon turned JOHANN F SIEMS into a coil a slight distance therefrom, and a 5' knob upon the end of the spring and bearing against the outer convolution of the coil, as set forth.
